Comment:

 av_read_frame() expects a blank AVPacket; you forgot to reset said packet
 in case avcodec_receive_frame() returns EAGAIN or EOF (your H.264 file has
 reordered frames, therefore there is a delay and the decoder does not
 immediately return an AVFrame.

 And your volatile is completely useless. And don't use Turkish for bug
 reports in the future.
